COIN-CONTROLLED FAN.

Application filed November 19, 1924. Serial No. 750,755.

, This invention relates to motor-operated fans of the coin-controlledtype, designed mainly for use in refreshment parlors and similar placesWhere customers, in warm weather, may desire to purchase the additional4comfort-of an artificial breeze.

The general object of the invention is to provide a simple, inexpensiveand entirely automatic device of the character specified whereby acustomer, by depositing a coin in the device, may obtain the operationof the fan for a limited period. Other objects are to provide a deviceof this character wherein vthe fan will have a bodily rotating move-`ment so as to distribute the breeze radially Vin a circle, to 4providea device which will automatically Vstart in operation upon the depositof the coin and will operate and automatically stop at` the end of apredetermined period, and to provide a device wherein a single electricmotor will both ro- .tate the fan on its own axis and also swing or turnthe fan bodily ,in a circular path.

Other objects and attendant advantages of the invention will be apparentto persons familiar with the art from the following detaileddescription, taken in connection with the accompanying drawings whereinI have illustratedinv structural detail an apparatus well adapted tofulfill the stated purposes and objects -of the invention and embody thei principle thereof, and in which-w Fig. 1 is an elevational view of thecomplete apparatus;

F ig. 2 is a vertical section of the parts below the motor and fan;

Fig. 3 is an enlarged cross-section looking downwardly on the line 3-3of Fig. 2;

Fig. 4 is an enlarged cross-section looking upwardly on the line 4 4 ofFig. 2;

Fig. 5 is a vertical transverse section on the Aline 5-5 of Fig. 4;

Fig. 6 is a vertical section on the line 6 6 of Fig. 4; and

Fig. 7 is an enlarged vertical cross-section on the line 7-7 of Fig. 4.

Referring to the drawings, 10 designates a base plate on which issecured, by screws 11, a circular sheet-metal housing 12. To the top ofthe housing 12 is secured, by screws 13, a circular plate or disc 14formed with an upstanding annular flange 15 overlapping and extendingsomewhat above the upper edge of the housing 12. Secured to the topofthe disc 14 is a smaller disc 16, in

the center of which is secured a collar 17 forming, with the discs 16and 14, a bearing and support for the lower end` of a central verticalstationary shaft 18. A 19 designates a circular sheet-metal casing of adiameter to fit loosely vat ,its lower end within the flange 15 andhaving secured in its upper end, as by screws 21, a conical cap or cover22. Attached to and depending from the top of the cap 22 is a longsleeve 23 having an extendedbearing on the shaft 18 and at its lower endattached by a'flanged collar 24 to a disc 25 fittedV Within the lowerend of the housing 19.` Encircling the lcollar 17 and resting upon andattached t0 the disc 16 by screws 26 (Fig. 3) vis a stationary spur gear27 made of insulating material. i

Mounted upon the upper end of the cap 22 is an electric motor 28operatinga directdriven fan 29. The motor 28 at its rear end is gearedto and drives a vertical'shaft31 ythat extends through an opening ,32.inthe cap 22 and is journaled at its lower end in a bearing 33 attached tothe under side of the disc 25. Keyed on the lower end of the shaft 31 isa spur pinion 34 meshing with the fixed gear 27. Manifestly, therotation of the shaft 31 by the motor 28, operating through the pinion34 and fixed gear 27, causes a rotation on the fixed shaft 18 ofthehousing 19, cap 22- motor 28 and fan 29.

Current is supplied to the motoras follows. Referring to Figs. 1 and 2,in the lower portion of the housing 12 is mounted an electric coupling35 for the circuit wires 36 and 37. From the inner end of the coupling35 a wire 38 extends to a binding post 39 (Fig. 4) on one side of thebifurcated stationary member 41 of an ordinary snap switch that ismounted on the under side of a bracket 42 attached to the bottom of theplate 14. From the other sideof the stationaryswitchmember 4 1 a `wire44 leads from a binding post 43 to a binding post 45 that, as shown inFig. 7, extends through an insulation block 46 on the-lower side of theplate 14, the upper plate 16, and the fixed gear 27 being encircled byan insulating sleeve 47. The upper end of the post 45 passes through andis rivetedI into a countersunk hole in a ring 48 (Fig. 3) of goodconducting material, such as copper, seated in an annular groove in theface of the gear 27. Attached to the under side of the plate 25 by aninsulated binding post indicated at 49 in Fig. 3 is a depending brush 51which wipes over the ring 48. From' the binding post 49 a wire 52 leadsinto the motor. The other wire 53 (Fig. 2)

from the coupling 35 leadsvtothelower ,side

of a binding post 45 similar inall respects to the binding post 45 andmounted` in other end of the block 46. The upper end ot the binding post45 isrivetedintoa smaller ring 54 (1* ig. 3) mountedin a vgroove in theupper face of the' gear 27 concentric with the outer ring 48. A^brushr55attached -to` the lower 4side of the lplate' 25 by an insulated bindingpost 49 similar to-tlie'b-inding post 49, sweeps fover the inner ring54. From the binding post 49 a wire `56 leads to the motor. Y A

57 designates the pivoted movable inein- 'ber ot'the snap switch thatcra-operates with the stationary member '41. `/Vhen thesnap switch isclosed, =the motor 'is 'i energized .through the described connections,and when the snap switch 'isiopemfthe circuit is-brolren. Coincontrolledateans for closing thel snap switch are illustrated :mainlylin Fig. 5,

Within 'the stationary tubularihousing 12 is mounted a nanrow casing 58containing a coi-n chute 59 .registering with a coin slot 61 in the Wallof the housing 12. In a suitable Aguideway below the chute 59 isslidably mounted a jpusher bar 62 having a head or 'knob 63 -on itsouter end.v vThis pusher bar isA normally 'retracted :bywa pull spring-64 (Fig. 2). When 'a coin, :such as tha-t indicated at 'C in Fig. l5is'inserted in the slot, falling in front of the pusher bar, 'thelatter, when pushed inwardly, 'causes'.the redge of the coin toengagewith andraise fthe heel 65 ofa trigger=66 mountedA on a pivot pin 67 andat its upper end canryingia pin 68 engaged with a slct69 in a link bar'.71. The forward endostrthelink barfi71is pivote'd at 72 to aqaivotedlever 73, the 'lower end of which is connected to and actnatesthepivoted member 57 ofthesnap switch in a wellknown manner,.-causingclosing xof the switch when the link 'bar 7l is pushed 'torwardly :asdescribed. The trigger 66, after the coin has passedfthe same, isretracted by a pull spring 74 2 .and 4) anchored at one end to apn 75 onthe trigger and at its otherrend to a post 76 in the housing 58.

The mechanism for automatically breaking the circuit and arresting thelmovement .ot the fan after '.a predetermined period of service is shownmainly i-n lFigsfi and 6, and

comprises the follow-ing.

In Aand depending 'from the bottom sid-e of the plate 14 is a screia7'77.'constituting a fixed shaft and support :for a pawl andratchettiming mechanism. Encircling the shaft '77 is a bushing sleeve 78(Fig. 6) on -which isrevolubly mounted the hub 79 ot a ratchet wheel 81.Fulcrnmed on the hub 7-9 -of the' ratchet wheel -81 is a lever, one

arm 82 of which carries on its free end a pivoted 'driving pawl 83, thelnose of which engages with the teeth of the ratchet wheel 81. The otherarm 84 of said lever extends upwardly obliuely.tliiough an opening 85(Figs. 3, 4 an 6) in the plate 14 and has mounted on its free end abutton 86 that lies abou-'e the plane of the upper surface of the plate114.1I Vlirttaclicdto and depending from the lower side of the rotatingplate 25 is an obliqu-ely dis-posed cam striker 87, clearly sl-iown inFig. 2, that, once during each revolution vot' .the fan support wipesover the button A86, rocking the pawl lever, and, through the pawl 83,turning fthe ratchet wheel 81 one tooth. The ratchet wheel is lockedagainst Aback-turning by a dog-ging pawl 88 (lFig. 4) pivoted vat 89 onthe plate 14 and having its 'ta-i191 connected by a pull spr-ing 92 withythe driving pawl 83; the spring 92 acting to urge both pawls intoengagement with the-ratchetfwneel. Secured `to the under side of .theratchet wheel -81 is a radiallyprojecting tappet arm 93vthat, onceduring each complete revolution of the ratchet wheel 81 strikes alaterally projecting pin -or stud 94 on the switch-actuating link 71,ret-racting said link (permitted by the slot 69) and opening the snapswitch; thus breaking the circuit. and stopping the fan.

The coins deposited drop int-o the hollow dish-shaped base 10,' whe-ricethey arc removed rom time to time by unlocking a door 95 (Fig. 1)guarding an opening'dn *100 the wall =of the stationaryliousing 12.

From the foregoing description Aand illus- 'trationit will be apparentthat :the fan is start-ed .in opera-tion Aby simply depositing -a. coinin the chute '59 and actuating thepusher 105 -bar 62 inwardly, thisclosing fthe motor. eircuit at the snap switch. The Imotor revolves theian and at the .same time sets up a relatively slow revolution of thefan 'support 19, 22,' causing the fan to move bodily in 110 a horizontalcircular path, thereby similarly distributing the current of air createdby the fan.. At each revolution of the fan support the 'ratchet wheel 81is advanced one tooth through eng-agement of the cam striker 87 with thelever button 86.. As soon as the ratchet wheel 81 makes one 4completerotation, the tappet arm 93 .strikes the .stud 94,

rand thereby opens the switch and breaks lill fications as fall withinthe spirit and purview of the appended claims.
